Measures of estimated subglottal air pressure and laryngeal air flow during speech production are compared for adults with normal laryngeal function and those with laryngeal abnormalities. The most traditional measure, air flow during sustained vowel production, is not a strong predictor of laryngeal function during speech production. Subglottal air pressure and laryngeal air flow offer insight into voice disorders and provide directions for therapy as well as a method for the quantitative assessment of treatment outcomes.

Perceptual-physiologic approach to evaluation and treatment of dysphonia.

The value of a perceptual-physiologic approach to both the evaluation and treatment of voice disorders is described and illustrated with an example of a patient with ventricular fold phonation. Objective measures are obtained to facilitate the understanding of the underlying pathophysiology and to document change over time. Evaluation data are recorded and interpreted collectively by a speech-otolaryngology team and may be valuable for medicolegal cases. Finally, the evaluation methods, particularly videolaryngoscopy, may be used for biofeedback purposes to facilitate voice therapy.

Restoration of intelligible speech 13 years post-head injury.

This case study demonstrates the efficacy of treatment of a patient with severe dysarthria long after the accepted period of 'neurological recovery'. A physiological approach to treatment was utilized and resulted in a change from non-verbal communication to functional verbal communication.
